PERFORATlNG-STAMP.

SPECIFICATION forming part of Letters Patent No. 225,043, dated 1llIarch2, 1880.

- Application filed November 6, 1879.

To all whom it may concern Be it known that we, J HN H. BARLOW and ISAAC TAYLOR, both of New Haven, in the county of New Haven and State of Connectiout, have invented certain new and useful Improvements in Stamp-Cancelers, of which the following is a specification.

Our invention relates to stamp-cancelers; and the improvements consist of a' short slotted cylinder provided with a cap clamping an elastic holder to the cylinder, of devices for adjusting the cutter and detaching the stamp, and of new combinations, as the above are hereinafter more fully set forth and claimed.

In the drawings, which we hereby make a part of this specification, Figure 1 is a vertical section through the center of the instrument, showing all its parts. Fig. 2 shows the cutter and the meansfor holding and adjusting the same. Fig. 3 shows the main part or body, to which ,all the other parts are directly or indirectly attached; Fig. 4 is a view of a short cylinder, its cap on one end clamping the elastic holder to the cylinder.

To enable others to make and use our improved instrument, we will describe its parts' and their operation.

' A, the main part or body, to which all the other parts are directly or indirectly attached, is a hollow cylinder having the spiral slot at near its lower end and the two enlargements on its upper end, as shown in Fig. 3. Into its upper end a perforated nut, 12, is screwed to form a bearing for a spiral spring. The screw m, Fig. 1, is inserted into this part, the head of which fits into the slot in the cylinder D and limits its movement.

The part B (shown in section in Fig. 1) is also a hollow cylinder, screws onto the smaller enlargement on the body A, and corresponds in. size with the greater enlargement.

D (shown in Fig. 4 and in section in Fig. l) isa short hollow cylinder, having the slot d to limit its movement bymeans of the screw m, Fig. 1, in the body A, and the cap E, Figs. 1

and 4c, clamping the elastic holder F to the This cylinder fits on the body A, as

cylinder. shown in section in Fig. 1, and is forced'outward by the spiral spring G.

3 and in section in Fig.1 by dots.) The holder F is made of india-rubber or other elastic ma- (Shown in Fig.

held in a position exactly vertical. The face may be inked, and the instrumentwill cancel with inkas well as in the manner hereinafter described.

The cylinder H, Figs. 1 and 2, fits in the perforation through the body A, is free to move in the same, and has its lower end made in the form shown in Fig. 2. It is perforated lengthwise and has the upper part of the perforation threaded. Into the cylinder H the screw 12, Fig. l, is inserted, the head of which moves in the spiral slot at, Fig. 8, and limits the longitudinal movement of the cylinder. Into the upper and threaded part of the cylinder the lower and threaded part of the rod I is turned, its end coming against the cutter M to adjust the same.

The spiral spring N (shown in Fig. 2 and in Fig.1 by dots) surrounds the rod I, its end coming against the cylinder H and nut I), Fig. 1, and pressin g the cylinder outward or downward.

' The cutter M is held in the cylinder H by the screw .90, Fig. 2, has teeth on its lower end,

as shown in the same figure, and is adjusted,

the screw 40 being loosened to cut the required depth by the rod The rod I has a perforation in its lower end, as shown in the sectional figure, into which the spiral spring 0 is inserted, which presses upon the pin y, passing through and below the cutter, to detach the stamp from the cutter .in case the stamp adheres to its teeth.

The parts being constructed and arranged as described, the holder, whether arranged in a machine or held in the hand, as the instru ment descends presses on the stamp, and the cylinder to which it is clamped is pushed into the instrument until the cutter, strikes the stamp, and the spiral groove, acting on the screw in the cylinder holding the cutter, rotates it and cancels the stamp. As the instrument is raised, the pin, passing through and below the cutter, detaches the stamp from the cutter in case it adheres to its teeth.

What we claim as new, and desire to secure by Letters Patent, is-

1. The body A, having the screw m, spiral spring Gr, cylinder D, provided with the cap E p and slot 01, and elastic holder F, projecting besisting of the body A, provided with the nut b, screw m, and spiral slot at, part B, cylinder D, having the slot d, cap E, elastic holder F, spiral spring G, cylinder H, having the screw n and removable cutter M, held in the cylinder by the screw a, spiral spring N, rod I, spiral spring 0, and pin 3 all the said parts constructed and in combination as shown and I5 set forth.
